EXTENSION TABLE.

Application filed June 7,

provements in and Relating to Extension Tables, of which the following is a specifica- .tion. 7

This invention relates to extensible-tables of the kind in which one or more extension leaves are adapted to be normally stowed away beneath a table top part or parts, and when such parts are drawn out from the cen ter or approximately the center of the table, the extension leaf or leaves are caused to rise into a position flush with the movable table top parts to extend the superficial area of Cal the table. v

More particularly the invention relates to extensible tables of the kind in which the usual runners or slides on the movable table top parts have pivotally attached thereto wedge pieces which each engage a reversed and corresponding wedge on the extension leaves, whereby they may be raised to extend the table top or stowed away therebeneath; In such a construction the lower edge of each slide or runner is formed with bayonet-like slots joined by a sloping part to permit the table top part to tilt, the'slots being adapted to successively engage a pin in the fixed table frame and thus form stops according. to whether the table is either closed or extended, a short reverse movement being necessary at the end-of the inward and outward movement respectively.

The invention consists in an improved ex} tension table of the kind above referred to in which the upper edgeof the runner or slide is formed with a recess for a part of its length to accommodate an extension leaf or leaves and the lower edge is provided with two abrupt stop-forming shoulders connected by a slightly sloping part whereby as said lower edge is drawn over the end member of the fixed table frame, it will cause the corresponding table top to rise and keep its under surface clear of the top surface of the extension leaf.

1923. Serial No. 644,042.

The invention will now be described with reference to the accompanying drawings, in which Figures 1 and 2 are respectively a plan and side elevation of another form of table closed;

Figure 3 is a vertical section of Figure 1 taken on the line 33;

Figures 1 and 5 are views similar to Figures 1 and 2 showing the table extended;

Figure 6 is a vertical section on the line 66 of Figure 5; f v

Figure 7 is an endelevation of Figure 4 with-the right portion broken away and' shown in-section of the same. a v

Referring now more particularly to the drawings, the two table top panels d are each provided with a pair of runners, those f of one panel (theleft in Figure 1) being arranged within the pair f on the other leaf, and preferably having their free or inner ends tied together by a batten 21. The right adapted to slide through slots in the upper parts of the legs 0 whilst the left hand pair f slide through one of the end members t of the fixed table frame. In addition to the usual side members Z) of the table frame an inner slide bar 22 is arranged parallel with, and spaced from, each side member Z), the ends of the bar 22 being carried by the end members t. v

The outer ends of both pairs of runners f or f are pinned or otherwise connected to their corresponding table panels ti, and each hand pair of runners f, (Figure 11) are of their upper edges are recessed to form a slide bar 22 It. will be seen from Figure 1,

for example, that the above described parts on one runner such as f are duplicatedfor the corresponding other runner f, the

tongue and groove connection therefor being arranged on the other side of the inner slide bar 22.

The extension leaves Z carry a pair of cleats 27 which are of similar but oppositely arranged wedge form to that of the wedge members 25.

The form of runner used in this modification is so formed on its under surface that it is not necessary to slightly overdraw it, but it is only necessary to pull it out to the exact extent required or to push it in and lock the parts together. For this purpose at or near the middle of each runner there is a shoulder 28 which forms part of a notch 29 which allows the runner to drop down over the end member t of thetable frame when. drawn out to full extent, the shoulder 28 acting as the limiting stop for the withdrawal movement. It is to be noted that the shoulder 28 has a forward wedge-like extension 30 for a purpose that will be explained. At its outer end the runner is shouldered at 31 whereby when the table parts are closed this shoulder drops down behind the frame member 2. and locks the parts together. Forward of the shoulder 31 the under surface of the runner slightly slopes downward to the notch 28.

The operation of extending the table is very simple. To withdraw one of the table top panels it is lifted so as to pivot upon its pin 24 at the far end, the rising movement being permitted by the clearance spaces 23 7 so as not to cause any raising of the extension leaf and the shoulder 31 being raised to clear the frame member t. The withdrawing movement now commences whereby the corresponding wedge members 25 are drawn beneath the wedge-like cleats to raise the extension leaf, but in order to prevent the under surface of the table top panel marking or scratching the polished upper surface of the extension leaf, they are kept apart by the sloping under edge of the runner while being drawn over the member 25. This ensures the separation and non-marking of the surfaces. At the end of the outward movement when the table top panel has cleared the extension leaf, and the latter has been raised into position, the shoulder 28 acts as a stop and the notch may then be allowed to fit over the member 2?, when owing to the wedge extension 30 which acts as a wedging heel-piece, as the runner is closed down, it is slightly forced inward to firmly clamp the extension leaf in between the table top panel at and centre panel a.

l/Vhilst the table is extended, the leaf or leaves remain solidly suported by the wedge members. 7 V

In closing the table, the runner is merely raised to disengage the notch 29 from the member t after which the inward sliding movement removes the wedge members 25 from beneath the wedge'cleats on the extension leaf, which is thereby progressively lowered till the ends of the leaf come to rest on the side members Z) of the table frame. All lateral movement of the leaf is prevented since the cleats are positioned between the corresponding runner on one side, and the inner slide bar on the other side, Figure 7.

From the above description it will be understood that the construction of the table is much simplified and can be made entirely in wood (although not necessarily) while each extending leaf may by a simple movement be freely lifted out of the table to expose any working parts for inspection. Dowel pins need not be used.

Having now described my invention, what I claim as new and desired to secure by Letters Patent is 1. An improved extension table comprising a fixed frame including side andend and leg members, a vertically movable extension leaf on the side members, a laterally extensible top above the extension leaf, runners connected with the top and slidable transversely through the fixed frame, the upper edge of each runner being provided with a recess for a part of its length to accommodate the extension leaf, the lower edge of each runner being providedwith two abrupt stopforming shoulders and a slightly sloping portion between the two shoulders, whereby as said lower surface is drawn through the fixed table frame, it will cause thecorresponding table top to rise and keep its under surface clear of the top surface of the extension leaf.

2. An extension table as claimed in claim 1 wherein the frame includes an additional side member adjacent each main side member and a wedge shaped memberpivotally connected on one side surface with the adj a cent runner and the other side surface being slidably supported in the adjacent additional side member of the frame. Y

3. Anextension table as claimed in claim 1 in which each runner is also formed with abrupt shoulders, one of which coacts with the end member ofthe frame to limit the outward movement of the runner while the other shoulder coacts with the same end member to lock the runner in its inner position, and a wedgingheel piece formed on the runner adjacent the stop shoulder which limits the outward movement for automatically tightening the extended parts of the table together, substantially as and for the purposesset forth. g

In testimony whereof I have signed" my name to this specification. A i
